Page speed is the measure of how fast the content on your site loads for a user. It is important because the pages that load faster are more efficient and offer a better on-page user experience. Google also considers page speed while ranking websites.
Many factors that affect or relate to page speed :
* Page size
* Images, video, and heavy files
* Excess code and Javascript
* Load time
* Time to First Byte (TTFB)
* Round Trip Time (RTT)
* Last Contentful Paint
